One of our customers was interested in pulling over the Due Date for a given Task over to their Sugar CRM and when I go to look for this field, I’m not seeing it on any related Task record in our cache and it’s not listed on the engagement API page here: https://developers.hubspot.com/docs/methods/engagements/create_engagement
Based on my testing, it appears that the timestamp field included in the engagement JSON represents the due date of the task. This is not to be confused with the createdAt and lastUpdated fields.
